Detailed explanation-1: -NI3 is polar by the effect of three different factors. The factors are electronegativity, shape and dipole moment. Though different between electronegativity between N and I atoms is little and create non-polar bonds, the lone pair on N makes the overall compound polar.
Detailed explanation-2: -Ammonia is a polar molecule because it has a positive charge on one end and a negative charge on the other. This makes it polar because the positive and negative charges are not evenly distributed. The reason ammonia (NH3) is a polar molecule is due to its uneven distribution of charges.
Detailed explanation-3: -A polar molecule is a molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. A diatomic molecule that consists of a polar covalent bond, such as HF, is a polar molecule.
